      Description

      we saw a job go into the ERROR state from an invalid state transition.

      It looks like we possibly got 2 TA_TOO_MANY_FETCH_FAILURE events. The first one moved it to FAILED and then the second one failed because no valid transition.

          Robert Joseph Evans added a comment -

          When a Job gets a JOB_TASK_ATTEMPT_FETCH_FAILURE it checks to see if the failure percentage is too high 50% or more of running reducers are complaining about it and at least 3 reducer attempts have tried to get the data and failed, it will send a TA_TOO_MANY_FETCH_FAILURE event to the map task attempt. The JobImpl stores the fetch failure count for each map attempt as it see the failures. If the failures get high enough to send the TA_TOO_MANY_FETCH_FAILURE event the JobImpl then deletes the failure state for the map attempt.

          The only scenario in which I can see this happening is a derivative of the following. Assume we have a single map task, and 6 reduce tasks. All six reduce tasks try to fetch from the map task at almost exactly the same time. They all fail and report back that they failed. After the first three report back the failure percent of running tasks is now exactly 50%, and is 3 or more, so the TA_TOO_MANY_FETCH_FAILURE event is sent and the state is reset. The next three reducer fetch failures are processed and we now have 3 failures which again is exactly 50%, and 3 or more total failures resulting in another TA_TOO_MANY_FETCH_FAILURE event being sent.

          There may be other situations too where the logic may get confused and it will send the event twice. I cannot think of any, but there may be others. We could either update the JobImpl to not send the event twice, or we could update the TaskAttemptImpl to handle getting it twice.

          This patch adds in the new state transition and ignores extra TA_TOO_MANY_FAILURE events. It also fixes a potential divide by zero in JobImpl.java
